Still waiting...
I know two people that have been denied already, so I'm thankful that I'm still alive. The admissions department said that it could be April before some people hear back, so it looks like we may have quite a long way to go for a definitive answer. That being said, it sounds like they've began cutting people. Both of the denials I speak of have visited the Academy before, so I'd say that if you've ever been, a denial is in your future; the common theory, and it is ONLY a theory, is that they are catering the program to people who have never been while still remaining on a competitive basis. (i.e. if you've ever been before, you're denied and if you haven't, than it's still competitive as usual.)
Again, this is just the theory I've heard floating around. I wouldn't exactly trust it or stress over it. Good luck to you! Hopefully I'll see you there!
